Key result
Microaxial LV assist catheters facilitate VT ablation in cardiogenic shock alongside advanced mapping and ablation.
Why the study?
Compatibility of microaxial left ventricular assist catheters with electromagnetic anatomical mapping systems and dual-energy ablation catheters for ventricular mapping and ablation had not been established.
Are microaxial left ventricular assist catheters compatible with electroanatomic mapping systems and dual-energy irrigated catheters for ventricular mapping and ablation in a porcine chronic infarct model?

This preclinical study assesses the technical compatibility of mechanical circulatory support (maLVAC) with advanced mapping and dual-energy ablation technologies in a porcine model.
Modern techniques for ventricular tachycardia ablation (VTA) incorporate advanced technology including electromagnetic anatomical mapping (EAM), dual-energy ablation catheters (DEAC) able to deliver radiofrequency (RF) or pulsed field (PF) ablation energy. Additionally, the advent of microaxial left ventricular assist catheters (maLVAC) have allowed for VTA in patients with cardiogenic shock.
